26 Claims.

This invention relates to a coin wrapper crimping machine, the purpose of which is to close one end of a cylindrical paper wrapper containing a stack of coins arranged in face contact. Wrappers of the general type referredixr,

are disclosed in United States Bateiit No. 2,205,283, issued to C. L. Downefb'iYJune 18, 1940. The machine of the present invention, however, will operate upon any more or less conventional form of wrapper which may require the closing of one end after having been charged character stated, which is simple, reliable, and

free from the need of frequent attention or servicing.

A further object of the invention is to include, in a machine of this type, means for accurately counting the coin wrappers operated upon and for exposing any attempt on the part of the operator to run coin packages through the machine without registration thereof. Also, means are provided for rendering the machine inoperative as soon as a predetermined number of coin packages have passed therethrough.

Another object is the provision of an effective signal or warning mechanism designed to aid the operator in limiting the output of the machine to a predetermined maximum, as established by a setting of the machine prior to placing it in operation.

Another object of the invention is to provide in a machine of the character referred to, efiective yet inexpensive means ensuring the operator against injury during operation of the machine, while at the same time effectively overcoming all efiorts to jam the machine and impair the accuracy or the continued proper operation thereof as intended. Themachine is thereby rendered foolproof and safe in operation.

Another object of importance is to provide a machine of the character stated, which may quickly be adapted for the crimping of coin wrappers of various diameters, that is, coin wrappers for the various denominations of coins in any money system.

The foregoing and other objects are attained by the means described herein and disclosed in v the accompanying drawings, in which:

For a proper understanding of the present invention, it is necessary to appreciate that the machine disclosed herein is adapted to operate upon a filled coin wrapper, which, by reason of a previous operation or manipulation, has been filled with coins and has had one of its ends closed or crimped to prevent passage of the coins from said closed or crimped end. The function of the instant machine, is that of accepting the filled coin wrapper, in the condition just mentioned, and operating upon the remaining open end for crimping it closed against the stack of coins held within the wrapper. The type of closure resulting from the operation of the machine, is very similar to that resorted to in finishing the slug end of a shot gun shell.

In brief, the machine comprises a suitable cabinet which houses the mechanism, and whi includes a top or cover plate 2, Fig. 9 of the drawings. and which will be referred to in regular order. The cabinet includes the side walls 3 and 5, which are spanned by a strut or plate 4A that supports a wrapper chute or guide 6, which is preferably in the form of a tube or well properly dimensioned to loosely receive a filled but unfinished coin wrapper fed into the open top 1 thereof either automatically or by hand. In descending through the chute or tube 6, the filled wrapper, with its upper end open, is directed onto a reciprocable carriage 8 which includes a clamp or holder that maintains the wrapper in an upright position, and thereafter, through the agency of a tripping means actuated by the wrapper in its descent, the carriage moves the Upright wrapper to a position beneath a crimping head which at a proper moment descends upon the open end of the wrapper and crimps it to the closed condition. Thereafter, the carriage again shifts, and directs the completed or closed package to a discharge port through which the package is ejected from the machine.

"Ihe foregoing constitutes the cycle of operation of the machine, which is repeated each time that a filled open-ended wrapper is dropped into the chute or well 6, or is otherwise fed to the clamping means of the carriage. Y

The foregoing constitutes a very general statement of the machine operation, and does not include reference to various auxiliary devices and refinements that characterize the completed machine.

Referring first to Figs. l to 4 inclusive, it will be noted that the machine comprises a main shaft III, the opposite ends 'of which are journaled in bearings II and I2 mounted upon the side walls of the cabinet. Upon the main shaft Ill there is rotatably mounted a worm wheel 13 and a clutch disc l4, these two parts being connected so as to rotate in unison. A worm wheel I 5 on the motor shaft l6 drives the worm wheel l3 and 'the clutch disc M. The motor M may be directly connected with the worm, for effecting a constant drive.

The upper end of shaft I 6 is adapted to carry a fixed pulley 11 which, by means of a belt l8, drives a second pulley [9 which is fixed to the shaft 20 of the crimping head 9. The sleeve 2| of the crimping head has a spline connection with shaft 20, so that the head may be elevated and lowered while rotating with the shaft 20 that drives it. The character 2| I indicates a gear case which may be charged with suitable lubricant for the worm and worm wheel.

It should be understood that the gear case and the bearings for shaft I6 are supported upon a bracket 22 fixed to the rear wall of thecabinet. A second bracket 23 carries the necessary bearing for the upper end of the rotatable shaft 20', and this bracket may be supported upon side wall 3 of the cabinet.

From the foregoing, it will be understood that so long as the motor M is energized, as it will be under normal circumstances, the crimping head will be rotated at high speed, while at the same time the'driving clutch element l4 will rotate with the wor wheel l3 which is secured to its hub.

The driven clutch part 24, which is splined to shaft ID for unitary rotation, is arranged to be engaged and disengaged from the driving clutch element [4 to determine the rotational cnm ping position,

by a shoulder 30 engagement with the stop or abutment 29, will permit spring 21 to urge the clutch elements into driving the main shaft I0. It will be understood also that a momentary lifting will permit the engagement of the clutch elements. Shortly prior to completion of a single rotation of the clutch elements, a cam face 34 of the rocker arm is struck by the stop 23, resulting in shifting the clutch element 24 to the right, to disengage the clutch in opposition to the force of the spring 21. In other words, tripping of the rocker arm move to the left, under the influence of spring 21, but before a full revolution has been completed, the abutment 29 will strike the inclined face 34 of the rocker arm, to shift the driven clutch element to the right, against the resistance of spring 21, and thereby disengage the teeth 35 of disc 24 from the teeth 36 of disc l4. Shoulder 30 normally abuts the stop 29, as shown, to maintain a disengaged relationship of the clutch elements.

'The means for momentarily displacing the rocker arm from the clutch disengaging position, comprises an electromagnetic means, which may be in the formof a solenoid 31, whose iron core 38 is retracted each time that the windings of the solenoid are energized by means of an electrical current. The outer end of the solenoid core carries a pivot pin 39 upon which is pivoted a link 40 which, at 4!, has a pivotal connection with one arm 42 of a bell crank lever pivoted at 43. The horizontal arm 44 of the bell crank lever has a free end 45 which may descend upon and depress the free end 46 of the rocker arm, in opposition to the force of a spring 41, each time that the electromagnetic means or solenoid is energized momentarily.

As was previously stated herein, the movement of a filled open-topped wrapper through the tube or well 6, initiates the operation of the machine. This is accomplished by causing the wrapper to initiate the energization of solenoid 31, and to this end the tube or well is provided with a trip lever 48 which may be pivoted as at 49 to the body of the tube or well, and a portion 50 thereof is disposed within a slot provided in the wall of the well or tube. The portion 50 extends into the well or tube so as to be struck by a descending filled wrapper, so that the trip lever 48 will be moved about its pivot 49 against the force of a small spring 5|, to cause a pin 52, which extends from the trip lever, to depress a switch button 53 of an electrical switch 54. The switch 54 is of the momentary contact type, and is opencircuitedby spring means. as is customary. The

contacts 55 and 56 of switch 54 (Fig. 8) are wired in series with the winding of the solenoid 31, so that electricity from the leads 51 and 58 will pass through the solenoid winding upon each momentary closing of the contacts of switch 54. As seen in Fig. 8, the circuit comprises the conductors 51, 59, switch contacts 68 and 6|, the contacts of switch 54, the solenoid winding 31, and the return conductors 62, 63, and 58. It will be seen also that the motor M is connected across the leads 51 and 58, so as to be constantly energized.

The switch 54 (Fig. 1) preferably is fixed upon an extension 84 of a bracket 65 which extends from the side wall 5 of the cabinet. This bracket supports other elements of the combination and which will be referred to later.

Up to this point in the description, it will be readily understood that the dropping of a filled wrapper, with its top open, into the guide or well 6, will by striking the trip lever 48 close the contacts of the switch 54 for energization of the solenoid 31, which in turn will momentarily lift the rocker arm 3| for effecting an engagement of the clutch disc, thereby to rotate the main shaft l8 with its cams 25 and 26 for carrying the wrapper through the crimping treatment and discharging it from the machine. The details of the mechanism for performing the crimping treatment will now be described.

As was previously stated, the filled wrapper in descending through the chute or well 6, drops vertically onto a reciprocating carriage 8 which is provided with holding means that grasp and clamp the leading or closed end of the filled wrapper. The carriage, through the medium of yoke lever 66 actuated by an irregular face of the cam wheel 26, is shiftable thereby for transferring the wrapper from the initial position beneath well 6 to a second position beneath the crimping head 9. For this purpose, the carriage is mounted for reciprocating horizontal movement along a stationary carriage bed 61 which may be furnished with a suitable guide rib or tongue 68 complementary to a groove in the carriage base, not shown. One end of the carriage carries a pivot bolt or the like 69, which as best seen in Fig. 5, furnishes a mounting for the free ends 10 and 1| of a pair of L-shaped jaw shifters which include the elongated fingers or extensions 12 and 13, The free ends 14 of said fingers preferably are rounded or tapered, so that bodily movement of the carriage to the left (Fig. 5) will cause the ends of the fingers to ride upon the convergent faces 15 of a stationary cam block 16 of the carriage bed 61. The ends of the fingers are constantly urged toward each other by means of a spring 11 (Fig. 4), the ends of which springs are secured to the studs 18 of a pair of brackets 19 and 80 each of which is fixed as at 8|, to one of the elongated fingers or arms 12 and 13. Accordingly, it will be understood that each movement of the carriage to the left will cause the spring 11 to urge the fingers together about their common pivot 69, as the free ends 14 ride down the inclines of the stationary cam block 16. Conversely, movement of the carriage to the right will effect a separation of the fingers, against the'force of spring 11, under the influence of the cam block faces.

To each of the elongated fingers 12 and 13,

' there is attached a jaw or holder, these being indicated at BI and 82. Each jaw or holder includes a pair of angularly disposed faces 84 and 85, of suitable width for bearing against the lower or leading end'portion of a filled wrapper dropped to the clamp or holder through the well 6, or otherwise lodged therein.

The jaw parts BI and 82 are so dimensioned as to receivebetween them a wrapper filled with coins of the largest denomination, when the fingers 12 and 13 are fully spread to their maximum extent by the cam block 16. fingers are permitted to converge, as will occur when the ends 14 are riding upon the cam inclines 15, the jaws will move with the fingers to reduce the size of the space between the jaws, so that wrappers containing coins of smaller denominations will be held between the jaws. In this manner, the clamp or holder is adapted for accommodating wrappers corresponding in diameter to the diameters of the various denominations of coins, without the need for manual adjustment. In other words, the jaws are selfadjusting for clamping and holding filled coin wrappers in an upright position, regardless of the diameters of the wrappers subjected thereto.

While it is immaterial what form of means is utilized for mounting the clamp jaws upon the fingers 12 and 13, there is shown by way of example herein a satisfactory connection for those parts. The connection comprises the way or groove 86 (Fig. 7) formed in the outer face of each jaw member, and an upstanding pin or stop 81 limiting the width of the groove at its middle section, so that space is provided between the pin or stop, and the wall 88 of the groove, for reception of a finger such as 12 or 13. In this respect, the jaws 8| and 82 may be identical, however, as indicated by Fig. '7, jaw 82 may include a pair of fixed straps 89 spaced apart so as to em brace the sides of the other jaw, as shown in Fig. 5. These straps perform only as a means of closing the rear and forward ends of the clamp or holder device, and they maintain the jaws in alignment at all positions of convergence of the fingers. By means of the construction illustrated, the jaws may have a rocking movement relative to their respective fingers.

Referring now to Fig. 4, attention is directed to the circular aperture 90, which constitutes the discharge port for coin packages that have been operated upon and completed in the machine. It will be seen that port 90, which is formed in the carriage bed 61, is not aligned with the opening established by the clamp jaws 8| and 82, and

.for that reason a filled wrapper which initially is placed within or drops into the jaws from the chute or well 6, will be unable to pass through the discharge port. Referring again to Fig. 4, it is to be understood that a filled wrapper inserted between the jaws will, by the first movement of the carriage, be carried to the left and will have its upper open end subjected to the crimping action of the crimping head 9. Thereafter, the carriage will move to the right, beyond the normal or initial starting position illustrated by Fig. 4, to align the space between the clamping jaws with the discharge port 80, so that the completed wrapper or coin package will drop through the discharge port and into the base of the cabinet, the clamping action upon the package having been released by outward spreading of the fingers 12 and 13 due to the camming action of the cam block 16. After the completed wrapper or coin package has dropped, the final movement of the carriage to the initial or normal position of Fig. 4, is effected by the cam wheel 26.

The action of the cam wheel 26 may readily be understood upon reference to Fig. 1, wherein When the v downward force of spring I01,

- the same purpose.

is illustrated an extension 9| on the yoke lever 66 at the opposite side of its pivot 92, said extension carrying a roller or other follower 93 adapted to ride upon the annular faces of the cam wheel. The Fig. 1 illustration shows the cam wheel in its initial starting position, at which the follower rests in a depression 94 of the cam, preparatory to ascending an incline 95 and riding upon a rather long track face 96, which results in swinging the yoke lever 66 for shifting the carriage 9 to the left, with the jaws directly beneath the crimping head 9. As the cam wheel 26 rotates through most of its movement, the cam encounters an extreme incline 91, which permits a rather powerful spring 99 to withdraw the carriage to the discharge position of the wrapper or coin package. The next movement is efiected by the incline 99, which leads the follower onto an elevated cam track section I00, which is immediately ahead of .the section 94. Although the incline 99 need not necessarily be as extensive as shown in Fig. 1, it is found that the provision of the cam section I00, afiording an extra final movement of the carriage, assists in disengaging the clutch discs to the fullest possible extent. Accordingly, a type of clutch construction other than that herein disclosed, might render unnecessary the elevated cam section I00, so that the cammight ride from the base of section 91 directly onto the initial starting section 94.

The connection between the carriage 8 and the lower end of yoke lever 66, may be efiected by means of suitable short links, as indicated at IOI.

Figs. 1 and 6 illustrate an acceptable formof means for lowering th rotating crimping head onto the open upper end of the filled wrapper, during the period at which the wrapper is positioned beneath the head. Said means may comprise a carriage I02 which rotatably supports the crimping head sleeve 2|, and which may be elevated and lowered -by means of a gear segment I03, the teeth of which engage the teeth of a rack I04 fixed on the carriage. The gear segment referred to preferably is rockably mounted upon a stationary pivot I05, and has at its free end a roller or other follower I06 which rides upon the peripheral irregular face of cam wheel 25. By preference, though not of necessity, the downward movement of carriage I02 is effected by means of a spring I01, the opposite ends of which abut the top of the carriage and the overhanging arm or bracket 23 which is directly above it. The carriage I02, as most clearly illustrated in Fig. 4, is vertically grooves I08. As should readily be understood,

rotational movement of cam wheel 25 will result in allowing the gear segment to move under the thereby lowering the carriage which carries with it the crimping head 9. The cam may be depended upon to limit .the downward movement of the crimping head.

It may be stated at this time, that the crimping head 9 is preferably detachable from its driving shaft 20, and is replaceable by crimping heads having different diameters designed to accommodate the various diameters of filled coin wrappers. It is to be noted also that the wrapper chute or well 6 likewise is readily replaceable by chutes or wells of diiierent inside diameters, for Thus, upon a requirement that the machine be utilized for operating upon a different size of coin wrapper, it is necessary only that the crimping head and the chute or well 6 be replaced with similar elements proporslidable within the guide tioned to accommodate another size of wrapper. The crimping head, as most clearly illustrated in Fig. 2, may consist of a series of segmental forming pieces I09 depending from the head and series of splines whereby the crimping head is the extension mounted upon its driving shaft 20 so as to rotate therewith, while at the same time permitting the elevating and lowering of the head with its carriage I02. Any suitable means may be provided for precluding, under normal conditions, any vertical movement of the head relative to the carriage. A very simple form of means for this purpose is indicated by the annular groove I I3 in the crimping head sleeve 2I, which groove may be entered by the end of a screw or other retaining device H4. The particular type of means employed for this purpose is immaterial to the invention, and may accordingly be designed in accordance with acceptable engineering practice.

Attention is now directed to the Fig. 9 drawing view, which illustrates a cover or top plate to be fitted bodily over and onto the top of the cabinet illustrated in Fig. 3. The cover or top plate carries on its upper surface a conventional type of counter II5 which records the number of operating cycles of the machine, and consequently the number of coin packages operated upon. Associated with the counter operating mechanism, is an interceptor in the form of a plate or flapper II6, for limiting or controlling the rate at which a succession of open-ended filled wrappers may be fed to the machine, this being accomplished by obstructing access to the wrapper guide or well 6 during the major portion of each operating cycle of the machine. The interceptor means functions also for interrupting or terminating the feed of wrappers into the machine, beyond the machine capacity, or beyond the amount for I which the machine has been set.

The interceptor IIG may be supported upon an arm II1 which at its free end is provided with a gear II8 disposed about the pivotal mounting II9 for the arm. A gear segment I20, mounted upon a shaft I2I which is journaled in a pair of brackets I22 depending from the cover or top plate 2, has its teeth in engagement with the teeth of gear H8. On the shaft of gear segment I20, there is fixed an extension I23 which is in the path of movement of-a trip lug I24, which lug may be fixed to any rotatable element on the driven side of the clutch, and preferably is carried by the carriage cam. When the lug I24 moves with the carriage cam 26, it strikes I23 and, through the agency of the intermeshing gear teeth, the interceptor II6 will be elevated to expose the well or tube 6 so thata filled open-topped wrapper may be inserted therein. It should be understood that the trip lug I24 is located at such a position upon the carriage cam, that at the beginning of every cycle of movement of the cam, and while the machine is at rest, the flapper or interceptor II6 will be held in an elevated position substantially at right-angles to the plane of the top plate or cover 2. Accordingly, it should be understood that as soon as the clutch is engaged, the trip lug I24 will pass the extension I 23 and thereby permit the interceptor to assume a closing position over the top of the well or wrapper guide 6,

In this connection, it should be understood that the power stroke of the trip lug is utilized in lifting the interceptor to the open position, and that closing thereof may be effected by gravity or, if desired, by a spring, so that there will be no danger of the interceptor injuring the fingers of the operator when it moves to the closed or well-obstructing position.

It will be found convenient to operate the counter lever I25 from a lever I26 on shaft I2I, through the agency of a connecting link which may be in the form of a tension spring I21. The counter preferably is one which will register on the up-stroke of its actuating lever I25, and it will be seen that the up-stroke occurs following the movement of trip lug I24 past the extension I23. The arm I" operates within an elongated slot I28 formed in the top or cover plate 2, and it will be seen that the spring I21 also extends through the top or plate.

From the foregoing, it should be evident that the interceptor and counter apparatus of Fig. is operated but once during each cycle of the the machine operation. Moreover, the interceptor remains in an obstructing relationship to the well opening throughout the major portion of the operating cycle of the machine, but is held in an inoperative or nonobstructing position so long as the machine is at rest. Accordingly, since the interceptor closes against the top of the well as soon as a wrapper has been placed within the well, there is no opportunity afforded for feeding more than one wrapper at atime into the well. The operating cycle of the machine is so rapid, however, that the machine will accept coin wrappers as rapidly as an operator can feed them by hand.

In addition to the counter and interceptor apparatus, the machine is provided with a metering device designed to limit the capacity of the machine according to the will of the operator. The metering device is illustrated by Figs. 9, 11 and 12. With reference to Fig. 9, I29 indicates a ratchet wheel mounted upon a stud I30 projecting downwardly from the under face of the cover or top plate, there being furnished a suitable means such as a spring I3I for urging the ratchet wheel always in a counter clockwise direction of rotation as viewed in Fig. 9. This ratchet wheel is furnished with a number of peripheral ratchet teeth as shown, which for purposes of illustration may total one hundred teeth. At varying distances from the center of the ratchet wheel, there is mounted upon said wheel a series of extending pins or lugs I33, I34, I35, and these may be located at definite positions with respect to certain ratchet teeth; for example, pin I33 may be at the twentieth tooth, pin I34 at the twenty-fifth tooth, and pin I35 at the fiftieth tooth of the ratchet wheel. At the one-hundredth tooth of the ratchet wheel there is fixed a radially extending bar or abutment I32. which in length equals or exceeds the combined diameters of the pins I33, I34 and I35. These pins or abutments, cooperating with the mechanism about to be described, may be utilized for limiting the output of the machine, as may be required.

The character I36 indicates a rocking lever pivoted at I31 upon a stud I38 (Fig. 11), which stud is shiftable within an elongated aperture I39 of the cover plate. The end of lever I36 nearest the ratchet wheel, carries an extending pin or abutment I40 which, upon shifting of the stud to various positions along the aperture I39,

may be placed in the path of movement of any one of the pins or abutments I33, I34, I35 or I32.

The object of so shifting the lever and its pins I40, is to cause a selected one of the ratchet wheel pins or abutments to strike the pin I40 as the ratchet wheel is rotated in clockwise direction, so as to tilt the lever I36 and thereby move the switch arm I4I of an electrical switch I42. The function of the switch I42, as will be explained in detail later, is to stop the machine and energizea warning signal I43, as soon as the machine has operated upon a given number of coin wrappers. The character I44 indicates an elongated slot in the free end of lever I36, for keeping the lever in operating relationship to the switch arm MI in all positions of adjustment of said lever I36.

To establish the proper adjusted positions for lever I36, there may be provided a frame or the like I45 on the upper or exposed surface of the top plate, said frame carrying a series of notches or stops I46 spaced apart in correspondency with the paths pf,.,travel of the ratchet wheel pins, thereby toienable a correct adjustment of the lever I36 and its pin I40, with respect to the paths of travel of the ratchet wheel pins or abutmerits. A lug or pointer I41 on the metering adjuster is adapted to engage any one of the notches I46 for establishing the location of the stop pin I40.

In the condition of the metering device, as illustrated by Fig. 9, intermittent rotation of the ratchet wheel in a clockwise direction, at each operating cycle of the machine, will bring the stop I32 around through a full rotation of the ratchet wheel, until at the one-hundredth tooth of the wheel the stop I32 will strike the pin I40, thereby to rock the lever I36 in a counter-clockwise direction about its pivot stud I38 to actuate the switch I42 and temporarily defunctionalize the machine. As will be evident, shifting of the pointer I41 to the second notch of the frame I45 would place the stop pin I40 in the path of travel of lug I35, so that the machine would be automatically stopped after having operated upon fifty wrappers. In like manner, disposition of the pointer I41 to the third notch would place the stop pin I40 in the path of movement of ratchet abutment I34, or, upon placing the pointer in the fourth notch, the stop pin would rest in the path of movement of ratchet abutment I33. It will be recalled that ratchet abutments I33 and I34 establish the location of the twentieth and twenty-fifth teeth, respectively, of the ratchet wheel so that operation of the machine would be limited to twenty or twenty-five cycles or crimping operations, depending upon the position of the stop pin I40 as determined by the pointer I41. An extra notch I460, or a series of extra notches, may "be furnished if desired, to dispose the stop pin I40 into the path of movement of any additional and intermediate ratchet wheel abutments, not shown.

In the event that the metering mechanism is to be rendered inoperative, so that continued uninterrupted operation of the crimping machine may result, there may be provided a means of latching the pawl release lever I49 to a position at which the pawls I50 and I5I will be withdrawn from their operative positions against the teeth of the ratchet wheel. The pawl release lever I 49, which is movable about a pivot I52, and which may be limited in its movement by means of a stop I53, may be held in the pawlretracted position by means of a button or other wheel tooth by tooth, in

6 latch element I54 that may be grasped and lifted after the lever has been rotated. to stand in the path of the lever and preclude the return thereof to the normal position of Fig. 9. It will readily be observed that the free ends I55 and I56 of the pawl release lever are operative against both pivoted pawls for disengaging them, upon a single rotational movement of the release lever in the clockwise direction. The pawl release is adapted to hold both pawls out of engagement at the same time, although one might release subsequently to the other. It should be noted that pawl I50 is furnished with any acceptable form of yielding means, such as a spring I51 which normally urges the pawl to the engaging position. The other pawl likewise may be furnished with a spring, for the same purpose.

In Fig. 11 is detailed the construction of the metering adjuster, and it is therein evident that the pointer I 41 forms part of a cup-shaped sleeve having a flange I48 which may be grasped and moved axially of stud I38, in a direction for compressing the spring I58, until the pointer I41 is removed from a notch I46, whereupon the stud shaft I38 may be slid lengthwise of the elongated slot I39 as previously explained. The knob I59 of the stud shaft may furnish a stop for the axial movement of the sleeve flange I40, and the washer I60 maintains the assembly in unitary condition. It is to be understood that the shank of stud shaft I38 is flattened at opposite sides so that it may not rotate within the elongated slot I 39, and that the sleeve whose flange is indicated at I48 likewise is fitted to the flat-sided shank for sliding movement without rotation. Thus, the pointer I41 is maintained always at right angles to the axis of the slot I39.

The pins indicated at I6I and I62 may be anchored in the top plate and properly located for limiting the rocking movement of lever I36. Lever I36 may be yieldingly maintained against the stop I62 by means of a spring I63.

Means are provided which advance the ratchet a clockwise direction of rotation (as viewed in Fig. 9), under normal operating conditions of the machine. Said means may constitute an oscillating lever I 64 having one end pivoted upon the stud its opposite end I65 movable from the Fig. 9 position to a position against a stationary stop I 66. The free end of lever I 64 carries the pivoted pawl I 50, and as will be understood, each successive movement of the lever into contact with stop I66 will cause the pawl to rotate the ratchet wheel a distance of one tooth. The movement of lever I 64 may be eil'ected through the agency of a link I61 which is pivoted thereto at the location I68, said link to be actuated each time that the machine performs a crimping operation. As is most clearly illustrated in Fig. 12, the forward end of link I61 may be pivoted as at I69 to a rock lever I10 that has a pivotal mounting I1I upon a bracket I12 which depends from the under face of the cover or top plate 2. A lug or extension I13 on the rock lever is normally disposed in the path of movement of an operating finger I14 operating finger may be fixed to the driven clutch disc 24. so that each rotational movement of said clutch disc in the clockwise direction (Fig. 12) produces a rocking of the lever I10 which is translated into a longitudinal motion of link I61, said link in turn operating upon lever I 64 to advance the pawl I I30 and having carried by any nearby rotational a distance equal to a single tooth of the ratchet wheel. The pawl I6I is a holding pawl, which maintains the ratchet wheel in the advanced positions to which it is moved by the driving pawl I60, in opposition to the force of spring I3I. understood that Bl to return the the initial starting position of I34. By proceeding to drop the filled open-ended wrappers in succession into the tube or well 6, the machine will operate the driving pawl I50 to intermittently advance the ratchet wheel until the pin or abutment I34, at the twenty-fifth tooth, strikes the stop pin I40 and moves the lever I36 in counter-clockwis direction about its pivotal mounting at I31. This action results in throwmg the actuating lever I of switch I42, for breaking the electrical circuit at 606I (Fig. 8), and establishing a closed-circuit condition "of a second pair 01' contacts I15 and I16. The breaking of the electrical circuit at contacts 606I, renders ineflective the switch 54 of the tube or well, so that it will be impossible to energize the solenoid or magnetic means 31 which normally initiates the clutch engagement at I424. Accordingly, the entire dered inoperative upon having performed the preselected twenty-five crimping operations, even though the driving motor M may remain in operation. With the breaking of. the circuit at contacts 606I, there is eiiected a closing of the electrical contacts I15 and I16, which permits a flow of electricity from lead 51 through said switch contacts, through the signal device I43, and back to lead 50 by way of conductor 63. This results in energization of the signal means I43, which may be either a visible signal such as a lamp, or an audible signal of known character. The switch contacts I15I16 will remain closed, and contacts 60-6I will remain open, so long as the ratchet pin or abutment I34 maintains a tilted condition of lever I36 against the stop I6I' (Fig. 9), by reason of impingement of said pin or abutment I34 against the pin I40 of the lever.

To condition the machine for subsequent operation, the operator need only to actuate the pawl release lever I46 to disengage both pawls I50 and I5I, whereupon the spring I3I will rotate the ratchet wheel back to the initial starting position. In the initial starting position, the switch contacts 60-6I will be closed, and contacts I15-I16 will be open, as illustrated by Fig. 8. In this condition of the electrical circuit, the filled coin wrappers will be effective for closing th switch 54 to restore the normal operating condition of the machine.

While it is immaterial what form of means is utilized for normally maintaining the pawl -actuating lever I64 in its position of rest against its stop or limit pin I11 (Fig. 9), the spring I51 which is attached to the driving pawl I50 may be utilized in the performance of that function. If desired, of course, a separate spring for the lever I64 may be provided, the one requirement being machine will thereby be renthat some form of yielding means be employed to return the lug I13 (Fig. 12) to the path of movement of the actuator I14 after each displacing movement of the member I13 by actuator With reference to the counter as disclosed in Fig. 9, the character [18 indicates a re-setting handle or knob for normalizing the counter to the zero reading. Referring to the pawls I50 and ll, as shown on the same drawing view, the character [19 indicates the pivot upon lever I64 which carries the pawl I50, whereas the character I80 indicates a fixed pivot for holding pawl I51. A structural brace for the side walls of the cabinet is indicated at l8l, Figs. 1 and 3.

The bottom of the machine cabinet preferably is open, so that a bag or other receptacle may be removably supported in position to receive the completed packages as they are released from the carriage and dropped through the discharge port 90. 7

As was stated earlier herein, the feeding of the 'filled open-ended wrappers to the machine may be either manual or automatic. In either case, best practice sometimes may call for elimination of the chute or well 6, with a direct deposit of such wrappers in the clamp or holder without the aid of guide means comparable to the chute or well herein disclosed. Thus, it is readily to be appreciated that the filled open-ended wrappers might be deposited in the clamp or holder successively without the intermediary of the chute or well, and the machine cycle initiated by means at the clamp or holder, corresponding to switch 54, or by a closing of switch 54 otherwise than by means of the wrapper. Actually, the switch 54 might be conveniently located for manual operation, or it may be actuated by a separate machine which feeds the wrappers to the clamp or holder. In a continuously operating crimping machine, neither the switch northe guide need be furnished of necessity.

In conclusion, it is pointed out that many of the machine parts and their arrangements are capable of considerable modification, and the substitution of various equivalents within the bounds of accepted engineering practice in machine design, is seen to be readily applicable. It is to be understood, therefore, that the machine herein disclosed represents but one of many possible arrangements or combinations of constituents that may be utilizedyin reduc ng the invention to a practical and useful form.
